This DDIC is also capable of upscaling an input image to the panel's native resolution, for example it can upscale a 1920x1080 input to 3840x2160 with either bilinear interpolation or pixel duplication. allOf: - $ref: panel-common.yaml# properties: compatible: items: - enum: - sharp,ls055d1sx04 - const: novatek,nt35950 description: This indicates the panel manufacturer of the panel that is in turn using the NT35950 panel driver.
